MACHlNE ton SCOURING GRAIN. I

To all whom it may cancer-a Be it known that I, DENNIS E. SIB Eg, acitizen of the United States of Americ residing at Chicago, in thecountyof Cook and .State of Illinois, have invented certain new and usefulImprovements in a Machine-for scouring Grain, of. which the followingis/"hv specification, reference being had therein to ,the accompanyingdrawings and the letters of reference thereon, forming a part of thisspecification, in which Figure 1 is a perspective view of the machinehaving a portion of its outer case broken away to show the interior,working parts.

Fig. 2 is a central vertical ection of the case of the machine and airnd view of rollers and endless brush-beltlwithin the case, and Fig. 3 isan end elevation of the machine, showing the Ineans'for connecting anddriving the roller brushes and for driving the belt brush.

I .Th-i's invention relates to certain improve ments in grain-scouringmachines, which im- PIOVBmGHiZS are fully set forth and explained in thefollowing specification, and claims.

Referring to the drawingsfA represents the outer case of the machine,having at inlet: spout B near its upper end and the dischargespouts Fand G near the lower end, thespout F being provided with asuctionfan-blower J for removing and discharging the dust from the grain, andthe spout G serves as an outlet for the cleaned grain.

D is an endless brush-belt mounted on the drums I P, arranged one nearthe top of said case and one near its bottom. It is intended that theupper drum shall be driven by means of belt 0 to'drive the said bolt inthe direction shown by the arrows.

S are brush-rollers arranged in a vertical train in front of thebrush-belt I) in such manner that their brushes intermesh with those ofthe'brush-belt.

' R are guide-rollers respectively arranged opposite the saidbrush-rollers against. the back of the brush-belt, and are for thepurpose of holding the belt against the brush- ;rollers. 'lhesebrush-rollers are intended to be driven in the direction shown by thearrows, but at lessspeed than the brush-belt, so that the brush of thebelt will pass rapidly between the brush 01' said rollers.

L are deflecting-boards arranged between each pair of brush-rollers, andare for respectively conducting the falling grain between thebrush-rollers S and the brush-belt D in its descent from onebrush-roller to ,the other. It is intended that the action of the brushot the belt and of the brush-rollerson the grain as it passesbetweenthem will scour *andpolish it and remove all and any object on: blesubstances from the grain, giving it brush-- ollers are shown as beingused, so that the gra u may be acted'upon several times in passingthrough the machine.

moving the dust and refuse matter that has a die 'n and :brightappearance. A series of The suction taiublower J is used for re beentaken from the grain, while the grain,

being heavier, will be discharged from the spout G. The roller brushesare each provided onthe outer ends of their shafts with worm-wheels \V,which mesh with worms Z end stepped in the beam E, and is boxed to theouter side of the machineby means of the boxes F Said shaft is providedon its upper end with bevelegear II, which meshes with bevel-gear 11' onthe drive-shaft J by means of which bevel-gears shaft J is rotated anddrives thesaid roller brushes. Bymeans of regulating the site of theworms and wormwheels the said roller brushes may be driven at diiferentspeeds if for any reason that is necessary.

on the vertical shaft J, which has its lower When it is desired to usethe machine as wire strong enough to remove the hulls and dead pointsfrom the grain.

The process for'scou ring the grain consists in passing the grainbetween the intermeshing brushes arranged to rotate toward each otherbut at different speeds, whereby the acan oat-clipper, the brushes maybe'made of tion of the brushes propels the grain through I brushes uponthe grain serves to remove-any objectionable substance from' it. Aseries of such roller brushes are used in connection" w th the beltbrush, so that the grain will be (It ted upon several times on its waythrough the machine so it will be thoroughly scoured before itsdischarge. Any number of roller brushes may be used, as before stated,and they may be rotated at different speeds it for any reason that is nessary or desirable; but it is always necessary to rotate the belt brushat a higher speed than the roller ln'ushes in order to cause the brushesto act upon the grain and propel it through between them as stated.

If desired, the guide-rollers may be substituted with a back board as abacking for the belt to hold it up in contact with the brushroliers; butthe guide-rollers are found to be preferable, so far, at least, asfriction is com corned.

in order to prevent grain from entering the fan-blower ease, a screen isplaced across its inner end and to agitate the falling; grain so as toseparate it from the dust the arms Z are used on the rear inner side ofthe spout t which enables the fan to remove therefuse matter in a bettermanner. The roller brushes S may be rotated in the opposite directionfrom that indicated by the arrows, if for any reason it might be foundbest when the machine is used on dill'erent kinds and quality of grain.

Having thus described my invention, what i claim as new, and desire tosecure by Lettt-rs Patent, is as follows, to wit:

1. in the egntin-st.'ourin machine shown and described, the eombinatitm,with the ease having the inlet-spout l3 and utltitflrfiptlllts l andi,of the drums l,brusli-belt I mounted on said drums, brush-rollers S,arranged in a vertical train against the said belt brush, so theirbrushes will intermesh with those of said belt brush and rotate at adifferent speed from tactwith said roller brushes, deflecting-floors L,worm-wheels arranged on the ends of the shafts of said roller brushes,shaft J, worms Z',soeu red on said shaft and arranged. to mesh with saidwornww'heels, and bevelgen-s ll ll and shaft .l'-', all arranged to0perate substantially as and for the purpose setv forth. 1

2.3. In the grain-scouring machine shownauddescribed, the combination,with the endless brush-belt l and roller brushes S, of the outlet'spoutI", having the fan J, the screen arranged across the inner end of saidspout, Y

and spent G, having the series of arms Z arranged to extend across itsinner end, substantially as and for the purpose set forth.
